What few I have sold, I haven't--and wouldn't--I would just geld them myself before selling. I personally do not want to get into refunding money somewhere down the road.
As a buyer a rebate is of little interest to me. Unless I know the seller I would be sceptical that i would ever see the rebate- it is easy to say they will refund money but I do believe there is a certain percentage if people who wouldn't actually refund the money when it came time to do so. So, I would bypass such an offer and buy a colt that had an acceptable price tag without any rebate. Goodness knows I've gelded more than my share of colts-some of which I've raised and some of which I have bought.
